快速夹紧的可换胀胎是根据我厂生产需要而设计的;在车床上使用这种胀胎加工套类零件的外圆,可以减少许多装卸工件的辅助时间,同时还可以提高工件的加工精度。可换胀胎由主体、蜗杆蜗轮、法兰盘、胀胎等零件组成,构造简单。胀胎结构可换胀胎的结构如附图所示。图中2是法兰盘,依靠内螺纹装在车床主轴上。1是主体,用螺钉15固定在法兰盘2上。7是丝杆,丝杆上的螺纹是30°的左旋梯形螺纹,头数2～3。5是蜗轮,内孔带有跟丝杆7同样的螺纹,装在丝杆7上。9是蜗杆,装在主体1上;蜗杆9跟蜗轮5啮合。6是蜗杆压盖,用3个内六角螺钉10固定
Rapid clamping of the swollen inflatable tire is designed according to my factory production needs; in the lathe to use this kind of inflation tire sleeve processing parts of the outer circle, you can reduce the handling time of many loading and unloading parts, but also can improve the processing of the workpiece Accuracy. Expandable tire by the main body, worm gear, flange, expansion tire and other components, simple structure. Inflatable structure Inflatable structure can be inflated tires as shown in the figure. Figure 2 is a flange, relying on the thread mounted on the lathe spindle. 1 is the main body, with a screw 15 is fixed to the flange 2. 7 is a screw rod, the screw thread is 30 ° left-handed trapezoidal thread, the first two to 3.5 is a worm wheel, the inner hole with the same screw thread 7, mounted on the screw 7. 9 is a worm, mounted on the body 1; worm 9 meshing with the worm gear 5. 6 is a worm gland, with three hexagon socket head cap screws 10 fixed
